Abstract
The invention concerns a seal device for a submersible machine, such as a pump or a mixer.
The seal device is designed as an easily replaceable unit comprising two mechanical face seals (4,6) and (5,7) resp. with an intermediate room for a barrier liquid in which a pump for circulation of said liquid is arranged. A spring housing (10) which serves as a uniting means for the seal device is provided with connecting means for the rotary seal rings (4) and (5) resp. and acts as a hub for impeller vanes (16) in said circulation pump.
